Radar and Nami are partial to carrot slices. They sniff at them in the beginning, but are soon chomping them down and racing back to the kitchen for another slice. They also get a little sliver of smoked ham once in a while… when I'm cutting up a ham steak for my omelet.
They're both big fans of chicken jerky (from Costco) and go totally nuts for a spoonful of cottage cheese on their dinner. We feed them dry food that we get at a feed store... Chicken Soup for the Dog Lover's Soul. They love it and its available in 35lb bags!
